Define Motivations, Don’t Define Implementation"—
I just read that post from Alan Klement at Medium. IMHO this approach is worth giving it a try.
Job Stories are great because it makes you think about motivation and context and de-emphasizes adding any particular implementation. Often, because people are so focused on the who and how, they totally miss the why. When you start to understand the why, your mind is then open to think of creative and original ways to solve the problem.
